9.3.1.2.1.1 Example
External synchronized image acquisition (high active)
Trigger modes
OnHighLevel
:
The high level of the trigger has to be shorter than the frame time. In this case, the sensor will
make one image exactly. If the high time is longer, there will be images with the possible
frequency of the sensor as long as the high level takes. The first image will start with the
low-high edge of the signal. The integration time of the exposure register will be used.
♦
OnLowLevel
:
The first image will start with the high-low edge of the signal.
♦
OnHighExpose
This mode is like
OnHighLevel
, however, the exposure time is used like the high time of
the signal.

9.3.1.2.2 Erase, exposure and readout
All pixels are light sensitive at the same period of time. The whole pixel core is reset simultaneously and after
the exposure time all pixel values are sampled together on the storage node inside each pixel. The pixel core is
read out line-by-line after integration.
Exposure and read out cycle is carry-out in serial; that causes that no integration is possible during read
out. The step width for the exposure time is 1 µs. Image data is then shifted out line-by-line and
transferred to memory.
